Answer:
x = 7
Step-by-step explanation:
The sum of angle measures in a quadrilateral is 360°.
(8x-5)° +107° +83° +119° = 360°
8x = 56 . . . . . . . divide by °, subtract 304
x = 7 . . . . . . . . . . divide by 8
Answer:
k=-2ax+10a+y,
Step-by-step explanation:
Can a vector have nonzero magnitude if a component is zero?
Yes, a vector can have zero components along a line and still have a non-zero magnitude.
Example: Consider a two dimensional vector 2i + 0j. This vector has zero components along a line lying along the Y - axis and a non- zero component along the X - axis. The magnitude of the vector is also non - zero.
Now, magnitude of 2i + 0j =
=2
